Div像推特一样水平调整大小

Question

I want to add functionality like in twitter when scroll down div elongates horizontally when click more button. How can i do so?

Answer 1

If you're referring to the tweet stream on twitter.com then it's a bit more complex than elongating a <div> . Behind the scenes what's happening is javascript running on the page make an AJAX call for more tweets. That data is then rendered to HTML and appended to the container <div> . In addition the "elongation" effect is likely an animation that simply alters the height of the newly appended content.

A great place to start is with jQuery and the Getting Started with jQuery tutorial .

Also worth checking out are the doc pages for:

• $.ajax
• $.append
• $.slideDown
